Using national surveys from 2015 and 2021, shows that more agricultural areas have higher home food production and neighborly sharing, and that interest in home production rose in urban areas after COVID-19—longitudinally demonstrating the multiple benefits of local food systems.

A contingent-valuation study at Ritsumeikan University, Japan, measuring the monetary value students place on student-led farming activities using double-bounded dichotomous-choice surveys of 375 students in 2016 and 356 in 2020, comparing each respondent's own willingness to pay (WTP) with the value they inferred other students would pay. In 2016 mean WTP was ¥1,613.6 (median ¥1,101.3) against a mean inferred value of ¥1,056.6 (median ¥742.4); in 2020 mean WTP was ¥2,376.8 (median ¥1,408.8) against ¥1,814.5 (median ¥1,150.6). Confidence intervals overlapped in both years, so the differences were not statistically significant, indicating less social-desirability bias than earlier research found. Estimated total utility was about ¥2.51 million, enough to fund the student-led agricultural project. Limitations: a single institution, no examination of the mechanisms behind inferred values, and hypothetical rather than actual donations.

This paper discusses the current status of the KIT Community Garden project, an honors project at Kanazawa Institute of Technology that began in 2016. The project aims to improve members' English language skills, gardening knowledge, environmental awareness, and establish a deeper connection to the community. The paper covers the garden's state, design principles, recent changes, feedback from current members, and outstanding challenges.

This study surveyed school garden managers at public elementary schools in an urban area of Japan to analyze school garden characteristics and influencing factors. Findings indicated that school gardens inside schools offer better safety but less community connection, while external school farms provide more agricultural experience space. Schools with both types showed stronger community ties but decreased safety, and a notable lack of budget, teachers, supportive policies, and manager motivation was observed in operating school gardens.

This article explores Utsunomiya University’s Eco-programs, which combine a pesticide-free community garden with an educational series, using ethnographic data. Findings indicate tensions between the Eco-programs' agroecological goals and other institutional goals at the university. Despite these conflicts, the programs provide a space for agroecological gardening and serve as an example of an alternative agricultural initiative in Japan.

A paper on the Kashiwabara House Grape Shippers Association, a member organization of JA Osaka Nakakawachi in Japan, examines what activities the member organization undertakes to demonstrate the cooperative's organizational strength, its functions and issues, and its future direction, based on a review of prior research and field interviews. JA Osaka Nakakawachi has natural conditions suitable for agricultural production but has been strongly affected by the urbanization of Osaka Prefecture; as a result, its agricultural management has developed in the form of urban agriculture, with farmland and management scale considerably smaller than the national average. Its main agricultural products are vegetables and fruit trees such as grapes.

With the public "Cooperative Agricultural Extension Program" in Japan facing growing budget and staffing constraints, and prior research pointing to a need for JA (agricultural cooperative) farm-guidance services to compensate for or substitute it in scale and function, this study (2023, Japan) examined JAs that administer urban agriculture through a review of statistical data, interviews with farm-guidance staff, and content analysis of disclosure publications from three Osaka Prefecture JAs, assessing the current state and potential of their farm-guidance services as a substitute provider. The analysis found that even for urban-type JAs, which can relatively easily build market-driven production and sales models, their farm-guidance services remain unable to adequately compensate for or substitute the public extension program in scale and function.

A study (2023, Japan) conducted a psychological-evaluation experiment in which participants viewed a 360-degree view of the landscape of rooftop gardens in the Shibuya commercial district of Tokyo, examining the relationship between spatial composition and psychological evaluation. Three axes were first identified from the psychological evaluations of the rooftop garden landscape. For inward-facing rooftop gardens, the comfort factor increased with larger floor area and more plants; for street-facing rooftop gardens, the comfort factor decreased when floor area was small and the view was dominated by buildings, roads, and fences with little vegetation.

Using 313 allotment gardens drawn from governmental open data, the study classified them by cluster analysis based on number of plots, plot size, contract price and duration, and facilities. It found that allotment-garden provision in Tokyo is differentiated from city center to suburbs by the share of agricultural land and residents' socio-demographic characteristics including population, share of young people, and income levels.

This paper examines design strategies for transforming leftover urban spaces by integrating creative and playful programs, using Tokyo, Japan, as a case study. Through ethnographic observations and spatial analysis, the study demonstrates how play positively affects everyday life in public spaces and enables extraordinary uses of these spaces. The findings offer guidance for urban planners and designers on how people use playfulness to appropriate and utilize leftover spaces.
